The main body 111 has an accommodating space 111a, one end of the main body 111 can be set as an open end, the other end is set as a closed end, and the inner space between the open end and the closed end is hollow to form the accommodating space 111 a. The extension portion 112 is integrally connected to one side of the main body 111 (e.g., the opening side adjacent to the receiving space 111 a), and the extension portion 112 is, for example, a protruding structure extending outward relative to the opening end of the main body 111. As shown in fig. 2, the extension portion 112 may have two position-limiting structures 112b, and the two position-limiting structures 112b are respectively formed on two opposite sides of the extension portion 112.
